Definitions

  • the invention relates to a conveyor system with at least one drive drum and / or reversing drum with a drum covering, and further with at least one conveyor belt, support rollers and support frames, wherein the conveyor forms a material-promoting upper run with a feed point for the conveying material and a mostly material-free lower run.
  • conveyor systems which are additionally loaded in the lower section.
  • Drive drums, reversing drums, buck drums and their drum pads are for example out DE 1 781 214 .
  • FR 2,113,824 describes a generic conveyor system.
  • drum pads for the drive drum and / or reversing drum and / or buckling drums as important components of a conveyor system exist, such as.
  • DD 267 474 A1 described, for the most part, of a rubber mixture comprising at least one rubber component or a rubber component blend, at least one crosslinking agent or a crosslinking system comprising a crosslinking agent and an accelerator, and usually further Mischingingredienzien, in particular at least one filler and / or at least one processing aid and / or at least one anti-aging agent and / or at least one plasticizer and / or other additive (eg fibers, color pigments). Due to the vulcanization of the rubber mixture, the drum coverings experience corresponding elastic properties.
  • the drum pads are usually cold on the individual drums (drive drum, reversing drum, buckling drum, support rollers, etc.) glued and serve for better power transmission to the conveyor belt, as slipping of rubber-metal by the mostly applied rubber coating on the drum, which serves as a drum pad is reduced.
  • the drum pad made of rubber and a mostly rubberized cover plate of the conveyor belt.
  • the circumferential force on the drive drum must be so high that it is able to frictionally drive the prestressed loaded conveyor belt.
  • the lining of the drums of belt conveyors therefore has a decisive influence on the maximum transferable torque and the belt life.
  • Slippage means that either the conveyor belt can not run optimally or that damage to the drum and to the conveyor belt can occur due to penetrating material to be conveyed between the drum surface and the conveyor belt.
  • the object of the invention is to provide a conveyor system, which is characterized by a reduction of damage to the drive drum and / or the reversing drum and / or the buckling drum and / or the support rollers and / or the conveyor belt. This results above all in an increased service life of the individual drums and / or the conveyor belt.
  • the foamed layer provides improved adhesion between the drum surface and the conveyor belt, especially when the foamed layer is directly on the surface of the drum pad. In this case, even on one additional profiling of the surface, such as in DE 28 54 583 A1 .
  • the presence of at least one foamed additional layer results in a weight reduction which has a positive effect on the costs and energy consumption.
  • polymer blend and rubber blend are used interchangeably.
  • the invention is fundamentally suitable for all conveyor systems and all types of drums or rollers, as used on a conveyor system.
  • correction rollers for pipe conveyor belt systems, support rollers, support rollers and deflection rollers.
  • the structure of the drum pad can be done analogous to that of a conveyor belt, which can be dispensed with any textile inserts and / or on the cover plates.
  • the drum pad preferably contains at least one cover plate on the surface of the drum pad.
  • the cover plate may in this case be formed as a film, be a fabric or be constructed of at least one polymeric material.
  • the cover plate is composed of at least one polymeric material, it is preferably a rubber which is selected from the group consisting of natural rubber (NR) and / or butadiene rubber (BR) and / or chloroprene Rubber (CR) and / or styrene-butadiene rubber (SBR) and / or nitrile rubber (NBR) and / or butyl rubber (IIR) and / or ethylene-propylene rubber (EPM) and / or ethylene-propylene-diene Rubber (EPDM) and / or polyacrylate rubber (ACM) and / or epichlorohydrin rubber (ECO) and / or chlorosulfonated polyethylene rubber (CSM) and / or silicone rubber (MVQ) and / or fluororubber (FPM).
  • NR natural rubber
  • BR butadiene rubber
  • SBR chloroprene Rubber
  • SBR styrene-butadiene rubber
  • NBR nitrile rubber
  • the rubbers mentioned can be used alone or in a blend.
  • the support-side and / or running-side cover plate is a foil or a woven fabric
  • the said materials can likewise be used here. It is particularly preferred if the film is constructed on the basis of at least one fluoropolymer. In this case, an additional optimized media resistance is ensured.
  • the cover plate may contain, in addition to the rubber component, at least one crosslinking agent or a crosslinking system comprising a crosslinking agent and an accelerator, and usually further Mischingingredienzien, in particular at least one filler and / or at least one processing aid and / or at least one aging inhibitor and / or at least one plasticizer and / or other additive (eg fibers, color pigments).
  • at least one crosslinking agent or a crosslinking system comprising a crosslinking agent and an accelerator
  • usually further Mischingingredienzien in particular at least one filler and / or at least one processing aid and / or at least one aging inhibitor and / or at least one plasticizer and / or other additive (eg fibers, color pigments).
  • the drum pad contains at least one textile insert, i. a single- or multi-ply textile structure, in particular in the form of a woven fabric, this preferably consists of cotton and / or polyamide and / or polyester and / or aramid and / or glass and / or basalt and / or steel.
  • the materials mentioned can be used alone or in the form of hybrid inserts, which are composed of at least one of the materials mentioned. Of particular importance here is a polyamide-polyester fabric.
  • the drum covering contains at least one layer of at least one polymeric material which consists of a foamed polymer mixture.
  • the qualitative and / or quantitative composition of the foamed polymer mixture, apart from the necessary blowing agents may hereby be the same as or different from the composition of an existing cover layer containing a polymeric material.
  • the qualitative and / or quantitative, in particular the qualitative, composition, apart from the necessary blowing agents equal to the composition of the rubber composition of the cover layer.
  • the rubber for the foamed polymer layer is selected from the group consisting of natural rubber (NR) and / or butadiene rubber (BR) and / or chloroprene rubber (CR) and / or styrene-butadiene rubber (SBR) and / or Nitrile rubber (NBR) and / or butyl rubber (IIR) and / or ethylene-propylene rubber (EPM) and / or ethylene-propylene-diene rubber (EPDM) and / or polyacrylate rubber (ACM) and / or polyurethane (PU ) and / or epichlorohydrin rubber (ECO) and / or chlorosulfonated polyethylene rubber (CSM) and / or silicone rubber (MVQ) and / or fluororubber (FPM).
  • NR natural rubber
  • BR butadiene rubber
  • SBR chloroprene rubber
  • SBR styrene-butadiene rubber
  • IIR butyl rubber
  • the foamed polymer layer may contain at least one filler in the usual amounts.
  • all fillers known to those skilled in the art such as, for example, silica, carbon black, mica, carbon nanotubes, silicates, aluminum hydroxide, talc, chalk, etc., can be used.
  • additives such as pigments, plasticizers, ozone and anti-aging agents can be used.
  • the vulcanization of the foamed layer is usually peroxidic, e.g. when EPDM is used as a rubber component, or as sulfur vulcanization using NR, BR or SBR or bisphenolic when using, for example, FPM.
  • the foamed polymer layer still contains at least one blowing agent.
  • blowing agents are usually pore-forming propellant gases such.
  • azo and diazo compounds referred to which split off under the influence of heat or catalysts gases (eg., N 2 or CO 2 ) and therefore serve to produce foamed polymer blends.
  • the blowing agents decompose at a certain temperature during processing to form gas or with the addition of volatile solvents during the polymerization or vulcanization. The foaming then takes place either when leaving the extrusion die, d. h by vulcanization in a UHF (microwave) hot air system or injection molding, or in open molds.
  • UHF microwave
  • blowing agents in particular of blowing agents based on at least an acrylonitrile polymer is obtainable shown, inter alia, under the tradename Expancel ®.
  • foam stabilizers can be added if needed.
  • Fig. 1 shows a conveyor system 1 in the form of a belt conveyor with a conveyed incagutholzgabe 2 and constructivegutabsch 4. Furthermore, the conveyor includes Oberertrumtragrollen 3, Untertrumtragrollen 7, a buckling drum 6, a reversing drum 9 and a drive drum 5.
  • Fig. 2 shows a cross section through a drum pad with a foamed layer 10, which is located between the underside pad 12 and top plate 13 of the drum pad, wherein additionally an embedded textile layer 11 is present and the additional foamed layer 10 in direct contact with the textile layer 11 and the Cover plate 13 is.
  • the cover plate 13 may in this case be formed as a film or as a rubber mixture
  • the lining underside 12 of the drum covering may in this case be formed on the basis of a rubber mixture or consist of at least one metal.
